First Post - looking at 1997 F350

Hi everyone, just registered.

just looked at a 97 today with 128k. Fresh trans rebuild and transfer case.

Anyhow, owner says it drips a bit. I crawled under and noticed a drop of engine oil hanging off the bellhousing. It is parked nose up, so I imagine all leaks would end up there. Being that the transmission was just rebuilt, can we rule out rear main?

What are the other common sources? Oil pressure sending unit, top left bellhousing bolt, etc? Trying to determine how easy or difficult it will be to fix.

Truck drives decent from what I can tell. my last trucks were 6.0 powerstroke, 5.4 s/c, and 4.2 v6. So I wasnt sure what to expect with the 460 in a cclb. gears feel tall, especially for a 350.

Thanks!

Common source on my 97 7.5L are the valve covers, however mine has only 31k mi. (Changing the gaskets soon)

Did need the transfer case fluid changed though as most of those miles were with a camper and pulling a boat with a few thousand pounds of fuel.

The only other leak I have is my water pump is weeping from a crack along a casting seam. I've noticed this issue come up in a few searches, but not sure how common it is.

Thanks. Maybe I should ask "What's the worst possible leak" lol

This could be a deciding factor of whether I buy this or not. Do not want a nightmare of a drip messing up my driveway. My wife, specifically. She's not very enthused over the truck purchase

The worst possible leak? One that comes from a cracked block.

It is heat that kills these engines, so other than messing up your wife's driveway with a work/hauling vehicle, coolant leaks are fairly serious. So the cooling system deserves an extra look, especially if the radiator has been changed, you will want to know why.

Run the VIN to find out the gearing and if it's what you want. Mine is a manual 4.10 as it was ordered just to go fishing with.

If you are not hauling all the time, you will want a faster, more economical ratio.

The door sticker says, and I don't doubt it after driving it.... C9 which is 3.55 LSD. Holy cow that's a tall gear.

Going to 35s or possibly 37s would necessitate a gear swap, no way around it. That's a pretty penny for an inexpensive truck

Well that's faster than me, fully loaded I pull 60ish mph max.

And a lovely 80ish mpg.

Either of those ratios will be faster and more efficient than mine. If you are pulling a heavy trailer once in a while, dropping 5000lbs in the box, or have a camper all summer, that ratio is a good compromise.

Oh, and as you might already know: the Cali version means it is mass airflow, federal is speed density.

I am searching for a cali computer and harness for mine, however I am fairly far from california.
